This episode of Horizon is about the future of micro-technology. In 1959, noted American physicist Richard Feynman offered a $1000 prize to anyone who could build an electronic motor no larger than half a millimetre on any side. He awarded the prize within eight months. Today, some scientists predict the imminent development of molecular computers the size of specks of dust. This program examines that and other technical possibilities, as it takes viewers on a guided tour of the cutting-edge laboratories of nanotechnology. There, scientists working on similarly astounding projects offer their predictions about future technological developments. Discussions include how nature provides scientific inspiration. Detailed scientific models and sophisticated computer graphics illustrate how these new micro-technologies will work.
